APPLICATONS
ZR-325 is used in ceramic glazes, optical glass, heat resistance porcelain and zircon refractories. Use of ZR-325 results in high opacity, craze resistance and colour stability for glazes used in tiles, sanitaryware and earthenware. Ruby Ceramics unique manufacturing process ensures constant opacity, due to the delicate balance maintained between the fine particle size and superior chemical purity.
